HOSE-COUPLING.

SPECIFICATION forming part of Letters Patent N 0. 726,077, dated April 21, 1903.

Application filed December 8,1}!02. flerial No. 134.396. (No model.) I

To all whom it may concern/.-

Be it known that I, LORENTZ LEHorzKY, a citizen of the United States of America, residing at McKeesport, in the county of Allegheny and State of Pennsylvania, have invented cerftain new and useful Improvements inHose Oouplings, of which the following is a specifiication; reference being had therein to the ac.- companying drawings.

This invention relates to certain new and useful improvements in hose-couplers; and the main object of the invention is to provide novel and effective means for easily. and quickly joining two sections of hose together.

This invention is particularly adapted for use in connection with fire-hose, though is by no means limited to such use, as it may be employed in any connection where it is desired to quickly and effectively join two sections of hosetogether.

Briefly described, the invention comprises a male and a female section. The female section is provided at its abutting end with a metallic collar integral with the section, andwithin this collar is an annular seat whichreceives a projection or annular flange onthe" The female section is alsOpro-j vided with a plurality of projecting lugs ,exr

her and provided on their underneath concave faces with grooves; The male member is provided on itsperiphery adjacent its abutting end with flanges, which are adapted to enter the grooves of the logs on the female section. After the sections have been secured together by a partial turn of one or the other of the sections, so as to interlock the flanges of the male sections with the lugs of the female section, the two sections or mem-- Figure 1 is a detail perspective view of my improved hose-coupler. Fig. 2 is a central longitudinal sectional-;view of the coupler in the coupled position, the hose being broken away. Fig. 3 is a detached end view of the female section; and Fig. 4. is a like view of the male section or member, showing the piv- .oted latch in the elevated position.

which is pivotally secured the bifurcated end .of a latch 6, provided on its underneath face,

near its free end, with a notch or groove 7.

The slot in the pivoted end of the latch 6 is of sufficient length to permit the entrance through said slot 8 of a 'turn-key 9, mounted for-rotation in the -male section or member adjacentto the lug or post 5, whereby it may be turned so as to bring the head of the key inalinement with the slot 8 to disengage the latchfi, and when the latch is closed the key is turned so as to bring the head transverse to the slot 8, and thus hold the latch in the locked position. i

The female section 2 is provided at its abuttingend withan annular integral collar 10, provided with an interior annular groove 11 to receive the projecting flange or annular tongue 3 of the male section or member. This female section or member is provided on itsabutting end with aplurality of projecting lugs, correspondingfto' the number of,,flanges 4 on the male section or member,these;proj ecting'l u gs 12 being formed integral with the collar 10-and hence lying above the plane of the section or'member. 1, so that the..latter may be received within thelugsI lQ.w'fThese lugs 2 are each provided on the underneath face with a curved groove or slot 14 to receive thecurved flanges 4 of the male section or member 1.

In operation the sections or members are joined together by matchingthe same, so that the flanges 4 will enter between the lugs 12,

and thus permit the flange or tongue 3 to enter the groove or recess 11, provided therefor in the female section. One or the other of the sectionsis then partially revolved or both sections or members are revolved in opposite directions, causing the flanges 4 to engage in the grooves of the projecting lugs 12, and thus lock the two sections or members together. The pivoted latch 6, which has been elevated prior to engagement of the sections or members, is then closed down, the collar fitting in the groove or notch 7, and the key 9 is then turned transversely of the latch, so as to hold the latter in the locked position. The hose is secured in the sections in any suitable or desired manner.

It will be observed that the coupling is easily and quickly effected and when made a perfectly water-tight joint is assured.

\Vhile the invention has been described in detail as to the construction, yet it will be evident that various slight changes may be made without departing from the general spirit of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A coupling comprising a male and a female member, a ring on the female member extending beyond the end of the hose-section thereof and engaging the periphery of the end of the male member, a latch pivoted to the male member and having the under face of its free end cut away to receive said ring, and means to lock said latch.

2. A coupling comprising a male and female member, the male member having flanges, and the female member having lugs receiving said flanges, a ring on the female member engaging the end of the male memher and a pivoted latch on the male member extending between two of said lugs and cut away to receive said ring, and means to secure said latch in engagement with said ring.

In testimony whereof I affix my signature in the presence of two witnesses.
